I did run the calcs. Here's the outcomes, with fleets on the left hitting fleets on the right:
Code:

Ter De Immune Immune Vulnerable Vulnerable Vulnerable Immune Immune Immune Vulnerable Vulnerable
Ter Bs Vulnerable Vulnerable Vulnerable Vulnerable Immune Vulnerable Immune Immune Vulnerable Immune
Cat Co Immune Vulnerable Vulnerable Vulnerable Vulnerable Vulnerable Vulnerable Vulnerable Immune Vulnerable

Zik Cr Vulnerable Immune Vulnerable Vulnerable Vulnerable Vulnerable Vulnerable Vulnerable Vulnerable Vulnerable
Etd De Vulnerable Immune Vulnerable Vulnerable Immune Immune Immune Immune Vulnerable Vulnerable
Etd Cr Vulnerable Immune Vulnerable Vulnerable Vulnerable Vulnerable Vulnerable Vulnerable Vulnerable Vulnerable
ie, Ter De cannot roid Ter Bs, but can roid Cat Bs. Attackers in my calcs hit downwards, at planets with 70% of their own value.
Fi: I don't think Phoenix is the ship to improve, to be honest. With Ter already fairly strong, I'd be more inclined to improve other races' anti-Fi. I'm looking at Vindicator, and maybe Thief.
De: The fortiness of De had crossed my mind at some point, but I'd forgotten it by the time I wrote my post. You're right, I think Ter De is fine, and Ranger is already pretty efficient, even against notorious anti-EMP fleets like Ter Bs. However, Co and Fr are in a good spot right now, neither too weak nor too strong. Improving Etd De by making it stronger against those Co and/or Fr doesn't solve the problem, just moves it. Not really sure what to do.
Cr/Bs: Bomber doesn't exist, I assume you mean Spectre? Both Xan fleets build it, so there'll be quite a bit of it around. I think part of the problem with Ter Bs is mostly in its defensive strength, as they naturally tend towards building the forty De ships for defense. I figure the strength of Ter Bs is closely tied to the weakness of Cr. And since both those fleets use good init against De and bad init against Bs, teamups can't save Cr. This is perhaps the only place where I'd be inclined to change inits, allowing the Zik fleet to do well against Bs (using a good init kill ship, ensuring they don't steal into Bs) and Etd against De (using their EMP ship).
